* The Moon is a Large, Dark Body: The moon is a giant rock in space. It doesn't produce its own light.
* Sunlight Reflects: When sunlight shines on the moon, some of it bounces off the surface. We see this reflected light as the moon's "glow".
* Phases of the Moon: The moon appears to change shape (wax and wane) because we only see the illuminated part facing us. As the moon orbits Earth, the angle of sunlight hitting it changes.
Think of it like a mirror: A mirror doesn't make light, it just reflects it. The moon acts like a giant mirror in space, reflecting the sun's light.
